After missing the last train home from work, I was invited to a drinking party by a single mother who was working part-time, and I ended up staying at her house. Shortly after I started drinking, I took a shower and the single mother came back, naked with only a bath towel on! Oh? Maybe she's inviting me...! I couldn't help but take her lips, squeeze her big tits, and insert myself! I had sex with the single mother who had been deprived of a man all night, and her libido was ignited after having sex for the first time in a while!
